Energy Management - Measurement for Energy efficiency and cost savings

For this application, energy needs to be measured in order to:

Table 13 of IEC TR 63213 describes the main related standards, as shown in Figure S2 below.

Energy efficiency aspects are dealt with in more details in Energy Efficiency in electrical distribution.

See also the recommendations provided in Focus on IEC 61557-12 standard.

NOTE Energy efficiency and cost savings, energy usage analysis is the process that allows a facility manager to assign energy consumption/costs to zones (plant, floor, workshop…) and to usages (HVAC, lighting, appliances, process…) over the time in order to allow optimization of energy consumption and energy costs.
